Thereafter, at step S 108 , operation control of the image in the memory is performed by the user. The process at step S 108 will be described later.
  • step S 109 determination is made on whether instruction is given from the user to start printing (more specifically, whether the start key is pressed at FIG. 13) or not.
  • steps S 107 and S 108 are repeated again.
  • FIG. 17 shows a sub routine for editing operation controlling process of step S 108 shown in FIG. 4 .
  • step S 201 image plane of color LCD 115 is switched to the state shown in FIG. 8 . Then, determination is made on whether the print key an the upper portion of the image plane of FIG. 8 is ON or not at step S 202 .
  • print key is ON
  • sample indicating the colors of the markers and the content of the editing processes corresponding to those colors is printed out as shown in FIG. 9 at step S 203 . Thereafter, process from step S 201 is performed.
  • step S 202 determination is made on whether a registration change key at the upper portion of the image plane shown in FIG. 8 is ON or not at step S 204 .
  • registration change key is ON
  • the image plane of color LCD 115 is switched to the state shown in FIG. 10 at step S 205 .
  • the process is halted, waiting for the OK button to be ON at step S 207 . Thereafter, when the OK button is turned ON, the changed content of the editing process is registered. Then, process from step S 201 is performed.
  • step S 204 determination is made on whether one of the frames 1 to 8 in the image plane of FIG. 8 is selected at step S 209 .
  • the ON key at the upper portion of the image plane of FIG. 8 is pressed after the user has selected frame 6 (step S 210 )
  • the image plane of color LCD 115 is switched to the state shown in FIG. 11 (step S 211 ).
  • FIG. 5 is a flow chart for illustrating the specific example for the memory operation controlling process of step S 108 shown in FIG. 4 .
  • document is read by the image reader at step S 1 .
  • the read data is stored in document reading memory 109 .
  • step S 2 determination is made on whether the marker display mode is selected in which the read document with markers thereon is displayed as it is, or the edited display mode is selected in which the document after being edited according to the marker is displayed.
  • step S 2 When it is determined that the marker display mode is selected at step S 2 (YES at step S 2 ), data corresponding to all of the colors are transferred from all of the planes 109 K to 109 B of the document reading memory to display memory 114 . Accordingly, the read document image is displayed on color LCD 115 as it is. Then, the image plane of LCD 115 is switched to the state shown in FIG. 12 at step S 4 .
  • step S 5 determination is made on if there is addition of area indicated with the marker by the user. This is a determination on whether the add key at the upper portion of the image plane shown in FIG. 12 is ON/OFF.
  • step S 5 the displayed image plane is switched to the state shown in FIG. 14 at step S 6 , the user adds an area through icon 201 , and the added area is displayed.
  • step S 6 After the process of step S 6 , the process from step S 5 is carried on again.
  • step S 9 determination is made at step S 9 on whether there should be any correction or change to the edited area specified by the marker at step S 9 and the area added at step S 6 . In other words, ON/OFF of the correct key at the upper portion of the image plane shown in FIGS. 12 and 13 is determined.
  • step S 9 the user makes corrections/changes to the area so that the result is displayed, at step S 10 .
  • step S 10 control (step S 10 ) of display process of corrected/changed area, with reference to FIG. 18 .
  • step S 9 when it is determined that correct key is ON at step S 9 , the image plane of FIG. 12 which had been displayed on color LCD 115 is switched to the image plane of FIG. 14 (step S 301 ). Then, determination is made on whether pen 800 is pressed onto any one point of the marker in the marker area displayed on tablet 116 (step S 302 ). If pen 800 is pressed onto any one point on the marker, the user moves this pen 800 on tablet 116 while still pressing the tablet with the pen (step S 303 ). Then, at step S 304 , detection is made on whether pen 800 is lifted up from the tablet or not. Thereafter, the coordinates of the point where pen 800 was lifted up from tablet 116 is recognized at CPU 110 and is stored (step S 305 ).
  • step S 306 the entire coordinates of the marker area is corrected in accordance with this recognized coordinates of one arbitrary point of the marker.
  • step S 307 a new marker area is developed in display memory 114. Then, the process is returned.
  • process is returned without allowing correction/change of the marker area.
  • step S 9 it is decided at step S 111 whether the area specified by the marker at step S 111 and area added, corrected or changed at steps S 6 , S 10 are determined or not. More specifically, this determination is performed by the user indicating the “OK” region (FIG. 14) displayed on the image plane by the pen.
  • step S 11 process from step S 6 is repeated.
  • the photocopier in accordance with the present embodiment has the following effects.
  • the operator can color the document with the marker referring to a sample in print indicating the relationship between the color of the marker and the process corresponding to that color.
  • the apparatus can be utilized more conveniently.
  • coloring can be done more accurately.
